In an experiment at the LISE3 facility of GANIL, we produced the proton-rich isotope {sup 22}Si by the fragmentation of a {sup 36}Ar primary beam at 95 MeV/nucleon. After implantation in a detector telescope, we studied the decay of {sup 22}Si via a measurement of charged particles emitted during the decay. The most important {beta}-delayed proton activity is observed at an energy of {ital E}{sub {ital p}} = (1.99{plus_minus}0.05) MeV with a branching ratio of (20{plus_minus}2){percent}. The spectra allow us also to determine the half-life of {sup 22}Si to be {ital T}{sub 1/2} = (29{plus_minus}2) ms. These results are compared with theoretical estimates and model predictions. {copyright} {ital 1996 The American Physical Society.}
